WiFi connection does not work with a battery on Espruino WiFi.

Sat 2018.10.06

Hello @JuanCar. There are many 'onInit' functions and 'quick start' examples.

'The code is unther the onInit fuction as the quick start example'

Would you please post the http: link as seen in the browser so we are able to follow along.

'but when I disconnect it and plug it to a battery of 3.7volts using pin + and - the wifi connection fail.'

Do we know if this is a software issue or a hardware one?

What is the voltage measured at the 3.3v pin adjacent to the VUSB + pin? This will show if the battery has sufficient voltage to allow the on-board regulator to function correctly.

Is the Espruino Wifi being recognized by other devices such as your PC or phone? Do they detect by name in their list of available recognized devices?

Was the code saved save() to the device before disconnect?
